Description

Technical Field

[0001] This utility model relates to the field of UV printer technology, and in particular to a UV printer with a plasma device. Background Technology

[0002] A UV printer, a digital inkjet device that utilizes ultraviolet curing technology, precisely sprays UV ink onto the surface of the substrate and instantly cures the ink through ultraviolet radiation. It has outstanding advantages such as instant drying, high color saturation, and wide applicability, and has been widely used in pattern printing in fields such as advertising signage, home decoration, and electronic product casings.

[0003] However, in practical applications, UV printers often face the challenge of insufficient adhesion when processing certain non-absorbent materials (such as plastics, glass, and metals). These materials have low surface energy or easily accumulate static electricity to attract dust, making it difficult for UV inks to fully wet and adhere firmly, resulting in problems such as scratches and peeling of printed patterns. To improve adhesion, existing technologies have attempted to introduce plasma treatment devices to activate and modify the material surface through plasma. However, traditional integrated plasma treatment modules typically have a fixed processing width and cannot flexibly adapt to materials of different widths, leading to a waste of energy and resources.

[0004] Therefore, we propose a UV printer with a plasma device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a UV printer with a plasma device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a UV printer with a plasma device, comprising a UV printer body, an assembly bracket provided on one side of the outer surface of the UV printer body, and a plurality of ion air bars uniformly and detachably fixedly connected to the inner top of the assembly bracket, wherein the air inlets of the plurality of ion air bars are all fixedly interconnected with pipe joints.

[0007] Several of the aforementioned pipe joints are threadedly connected to manual valve assemblies, and the air inlet ends of several of the manual valve assemblies are fixedly interconnected with a long pipe. The end of the long pipe is fixedly interconnected with an air supply assembly, and the air supply assembly is fixedly connected to the UV printer body.

[0008] A guide roller is provided below several of the ion air bars, and the guide roller is rotatably connected to the assembly bracket.

[0009] Furthermore, the mounting bracket includes two connecting frames, both of which are fixedly connected to one side of the UV printer body. A mounting frame is fixedly connected between the two connecting frames, and the two ends of the guide roller are rotatably connected to the inner walls on both sides of the mounting frame. The guide roller has a guiding effect on the substrate.

[0010] Furthermore, each of the outer surfaces of several of the ion air bars is fixedly fitted with a mounting plate, and the mounting plate is fixed to the mounting frame by several bolts. The arrangement of the bolts and the mounting plate facilitates the disassembly and assembly of the ion air bars.

[0011] Furthermore, several of the manual valve assemblies include a front connecting pipe, and the pipe joint is threadedly fitted onto the outer surface of the front connecting pipe. One end of the front connecting pipe is fixedly connected to a manual ball valve, and the other end of the manual ball valve is fixedly connected to a rear connecting pipe. The rear connecting pipe is fixedly connected to the long pipe, and the manual ball valve can control the connection between the long pipe and the ion bar.

[0012] Furthermore, the air supply assembly includes a support frame, which is fixedly connected to one side of the UV printer body. A centrifugal fan is fixedly connected to the top of the support frame, and the air outlet of the centrifugal fan is fixedly connected to a long pipe. The support frame provides support for the centrifugal fan, which is beneficial for the installation of the centrifugal fan.

[0013] Furthermore, the centrifugal fan has a threaded seal connection to the air inlet end with a stainless steel filter cartridge, which can filter the incoming air to ensure the cleanliness of the incoming air.

[0014] The beneficial effects of this utility model are:

[0015] In use, this invention features multiple detachably connected ion air bars and independently controlled manual valve components, allowing for flexible adjustment of the plasma treatment width to adapt to different printing substrate widths and avoid energy waste.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a UV printer with a plasma device is disclosed, including a UV printer body 1. An assembly bracket is provided on one side of the outer surface of the UV printer body 1. The assembly bracket includes two connecting brackets 2, and both connecting brackets 2 are fixedly connected to one side of the UV printer body 1. A mounting bracket 5 is fixedly connected between the two connecting brackets 2. A plurality of ion air bars 8 are uniformly and detachably fixedly connected to the inner top of the assembly bracket. A mounting plate 15 is fixedly sleeved on the top of the outer surface of each plurality of ion air bars 8, and the mounting plate 15 is fixed to the mounting bracket 5 by a plurality of bolts 14. Mounting holes matching the bolts 14 are opened on the mounting plate 15, and screw holes matching the bolts 14 are opened on the inner top of the mounting bracket 5.

[0025] The air inlets of several ion air bars 8 are all fixedly connected to pipe joints 11. The pipe joints 11 are existing pipe fittings, which are standard parts on the market.

[0026] Several pipe joints 11 are threadedly connected to manual valve assemblies. The air inlet ends of several manual valve assemblies are all fixedly connected to a long pipe 6. Several manual valve assemblies include a front connecting pipe 12. The pipe joint 11 is sealed and threaded onto the outer surface of the front connecting pipe 12. One end of the front connecting pipe 12 is fixedly connected to a manual ball valve 4. The other port of the manual ball valve 4 is fixedly connected to a rear connecting pipe 13. The rear connecting pipe 13 is fixedly connected to the long pipe 6. The manual ball valve 4 works by rotating the ball 90 degrees to achieve full opening or full closing. When the ball contacts the valve seat sealing surface, it can cut off the flow of the medium.

[0027] An air supply assembly is fixedly connected to the end of the long pipe 6, and the air supply assembly is fixedly connected to the UV printer body 1. The air supply assembly includes a support frame 10, which is fixedly connected to one side of the UV printer body 1. A centrifugal fan 3 is fixedly connected to the top of the support frame 10. The outlet end of the centrifugal fan 3 is fixedly connected to the long pipe 6. A stainless steel filter cartridge 9 is threadedly sealed to the inlet end of the centrifugal fan 3. The outer surface of the inlet end of the centrifugal fan 3 is provided with an external thread. A threaded sleeve is fixedly welded to the mounting end of the stainless steel filter cartridge 9, and the threaded sleeve is threadedly connected to the external thread. A sealing ring that abuts against the outer wall of the centrifugal fan 3 is fixedly connected to the end of the threaded sleeve to ensure the sealing between the stainless steel filter cartridge 9 and the centrifugal fan 3.

[0028] Several ion air bars 8 are provided with guide rollers 7 below them, and the two ends of the guide rollers 7 are rotatably connected to the inner walls of the two sides of the mounting frame 5. The inner walls of the two sides of the mounting frame 5 are fixedly connected with bearing seats, and the inner ring of the bearing built into the bearing seat is fixedly sleeved on the outer surface of the guide rollers 7.

[0029] Working principle: First, the operator can flexibly adjust the number of ion air bars 8 used according to the width of the current printing substrate. For areas covering the width of the substrate, the corresponding manual ball valve 4 is opened to supply airflow.

[0030] The centrifugal fan 3 in the air supply assembly is started. The centrifugal fan 3 draws in air from the outside and filters it through the stainless steel filter cartridge 9 installed at its air inlet to remove dust and particulate impurities from the air, ensuring the supply of clean air. After being pressurized by the centrifugal fan 3, the clean air is sent into the long pipe 6. The long pipe 6 serves as the main air supply duct, distributing the airflow to each manual valve assembly. Then, it passes through the rear connecting pipe 13, the manual ball valve 4, the front connecting pipe 12, and the pipe joint 11, and finally enters the interior of each ion air bar 8. The ion air bar 8 uses the internal high-voltage electric field to ionize the air passing through, generating a large number of positive and negative ions, forming a low-temperature plasma, which is then blown out evenly from its outlet.

[0031] Guided and supported by the guide roller 7, the substrate to be printed smoothly passes beneath several ion air bars 8. The plasma stream blown out by the ion air bars 8 continuously and uniformly impacts the substrate surface. This process has a dual effect: the plasma stream can effectively blow away tiny dust particles and electrostatically adsorbed impurities on the substrate surface; the high-energy particles in the plasma undergo physical and chemical reactions with the molecules on the substrate surface, which can significantly increase the free energy of the substrate surface and improve its wettability and adhesion.

[0032] The cleaned and activated substrate, after plasma treatment, then enters the printing area of ​​the UV printer body 1. UV ink is precisely sprayed onto the substrate surface and immediately cured by UV light. Due to the plasma treatment of the substrate surface, the adhesion between the ink and the substrate is greatly enhanced, effectively avoiding problems such as fading and scratches of the printed pattern, and significantly improving the durability and quality of the printed product.

[0033] When a particular ionizer bar 8 needs cleaning or malfunctions, it can be disassembled and replaced independently. The specific procedure is as follows: loosen the pipe joint 11 at the connection point to separate it from the air circuit, and finally unscrew the bolts 14 that fix the mounting plate 15 to the mounting bracket 5. Then, the ionizer bar 8 can be removed. After replacing it with a new ionizer bar 8, install it in the reverse order.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
